Yields of by-products from different cattle types.
Slaughter cattle (n = 360), selected and allocated to types according to their phenotypic breed type characteristics, were slaughtered in lots of 15 head at a large commercial packing plant. By-product weights were obtained for these lots of 15 head after plant personnel had separated the by-products according to plant procedures. Percentage of slaughter weight in each by-product was calculated. The trait most influenced by cattle type was the hide; Bos indicus cattle generally had the greatest percentage of their live weights as hide (green, trimmed, fleshed or cured), and Holstein cattle generally had the lowest. For edible by-products, the liver differed significantly among cattle types, with Holstein cattle having the higher percentage of their live weight as liver. Other items studied were not significantly or economically different among cattle types.
